Real Madrid playmaker Isco has reached an agreement in place to sign a new deal at the Santiago Bernabeu until 2022, according to Cadena Ser. Yet the Spanish radio station claims that his long-term future at the Champions League winners remain uncertain amid recent speculations linking him with a move to Tottenham Hotspur and Chelsea.

Gareth Bale, Lucas Vazquez, Luka Modric and Toni Kroos have all committed their long-term future to Real Madrid in recent weeks as part of a campaign of contract renewals at the Santiago Bernabeu.

Cristiano Ronaldo and Pepe are expected to follow the same footsteps in the coming days while Cadena SER are now claiming that Isco and right-back Dani Carvajal will go next – despite the playmaker's long-term future at the La Liga leaders remains up in the air.

The decision has an explanation though as the Spanish international's current contract at Real Madrid is set to expire in the summer of 2018. This means that the La Liga giants will need to negotiate his departure on the cheap at the end of the current season in order to avoid losing him for free the following summer.

Cadena SER reports that Real Madrid have thus decided to extend the 24-year-old's contract until the summer of 2022 in order to avoid that situation. This way, even if Los Blancos decide to sell the player in the near future, they will be in a better place to negotiate his sale.

The news comes after earlier this week The Mirror reported that Tottenham are still interested in luring him to White Hart Lane on loan during the coming January transfer window, while Chelsea would also join the race if Real Madrid decide to negotiate his departure.

Isco was already heavily linked with a move to Spurs during the summer as Real Madrid then reportedly tried to part ways with him to make space for the promising Marco Asensio, who returned to Zinedine Zidane's side following a impressive loan spell at Espanyol.

The Mirror reported in the dying days of the transfer window that Tottenham considered his arrival to the Premier League on loan, with an option to buy him next summer. AS later on deadline day backed up the claims, adding that Mauricio Pochettino had personally approached the player to lure him to Spurs.

Isco finally decided to stay at Real Madrid to keep fighting for a regular place in Zidane's plans. The former Malaga star has took advantage of Modric's injury to be in the starting line-up in recent games but earlier last month admitted he could leave Real Madrid in the summer should he fail to get established at the La Liga giants this season.

"I'm 24 and if I don't find a place in the starting line-up, I'd like to move. I know what I can do well and if not here, then I'd like to be able to do it elsewhere. I'm happy in Madrid, but what footballers want is to progress and if I can't here, I wouldn't have a problem in looking for an exit," Isco said during an interview with Cope, adding that a move to Premier League could be on the table in that hypothetical case.

"I still have time to think about it. I'm very happy at Real Madrid, but it is true that the choice of Malaga is there, it is my home. I like the Premier League a lot but I think about it as an option for the future. Now I'm only thinking about improving and working hard to earn a place in the Real Madrid line-up. "
